API Shopify Connection Issue and Runtime Error

I am trying to update the description of my Shopify products using this flow (around 200 products per collection). The issue is that my flow stops running after 45 minutes so I can’t edit the whole collection.

This means that I can’t run it again without re-modifying the same products twice (as Make doesn’t have memory of which products have already been treated)? Any tips on how I can run this flow for all my products without running out of time?

Also, I have this error for other collections. Would you know what causes this issue:

  • [API] This action requires merchant approval for write_products scope.

Thanks a lot in advance!
